' KEY-RING.

Application filed August 5, 1916.

To all whom it may concern: Be it known that I, MORRIS SAro, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Key- Ring, of which the following is a full, clear, and exact description.

My invention relates to a key ring. The object thereof is to provide a simple, strong and efficient ring which cannot open accidentally and which can be easily and quickly manipulated to place upon or remove therefrom a key.

WVith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of my key ring;

Fig. 2 is an elevation of the ring with the front wall of the lock thereof removed to show the details of construction;

Fig. 3 is a similar view showing the locking member displaced to permit the disengagement of the ring from the locking means, the dotted position showing the ring open; and

Fig. 4: is a cross section on line 4- Fig. 2.

Referring 'to the drawings, 5 is the ring which has a gap 6 whereat the ring has outwardly extending portions 7 and 8 forming lugs lying in the plane of the ring. The lugs 7 and 8 fit into the upper end of a lock housing 9, the lugs 7 being secured to the housing by a pin 10 forming a hinge. The lug 8 has a slot or end notch 11 which engages a pin 12 carried by the housing.

To disengage the notch from the pin 12, the ring must be sprung as shown in the left-hand dotted line in Fig. 3. The giving of the ring is normally prevented by a block Specification of Letters Patent.

13 fitting into the gap 6 of the ring and carried by the housing 9. The block is maintained within the gap by a spring 14, one end of which abuts against the block 13 and the other against the bottom of a U-shaped member 15 carried by the housing 9 and which member constitutes a guide for the block 13. The block 13 has a pin 16 which projects through a slot 17 provided in the housing, so that the block may be pushed out of the gap when it is desired to place a key on or remove a key from the ring, for which purpose it would be necessary to clear the gap, that is, to throw the ring to the position as shown in the right-hand dotted line in Fig. 3.

The U-shaped member 15 has preferably a portion thereof extending out of the housing 9 wherein an aperture 18 is formed so that a chain may be attached thereto to facilitate the carrying of the key ring.

From the above description it will be seen that my key ring cannot be accidentally opened, for the block 13 lies normally in the gap 6 of the ring 5.

I claim:

1. A key ring comprising in combination a yielding ring having a gap, lugs projecting outwardly from the ring at the gap, a housing hinged to one of the lugs and adapted to engage the other, said other lug hav-. ing a notch, a pin in the housing adapted to snap in'the notch, a U-shaped member within the housing, a block slidably mounted within the U-shaped member, a spring for moving the block into the gap radially of the ring, said housing having a slot, and a pin projecting from the block through the slot whereby the block may be moved out of the rings gap, substantially as and for the purpose Set forth.

2. A key ring comprising in combination a yielding ring having a gap, lugs projecting outwardly from the ring at the gap and lying in the plane of the ring, a lock housing hinged to one of the lugs, said housing having a pin, said other lug having a notch into which the pin is adapted to snap, a U- of the U-shaped member into the gap of the ring radially of the ring when the gap of the ring is in alinement with the block, said housing having a slot, and a pin projecting from the block through the slot whereby the block may be moved out of the rings gap 1 and the ring sprung to disengage from the look housing.
